Barley Yellow Dwarf Virus Translocation in Wheat and Oats¹

We studied the translocation of barley yellow dwarf virus in two soft red winter wheats (Triticum aestivum L. em. Thell.) and three spring oat (Arena saliva L.) cultivars and lines. Plants grown under ample soil moisture or moisture stress were infected with a local field collection of barley yellow dwarf virus. Nonviruliferous (test) aphids were then attached to sampling sites on emerging and fully emerged leaves at various times after infection. Virus movement was similar for all cultivars in our test. Virus was transferred to test plants from each sample site in each cultivar. As the plants grew, virus could be detected in the leaves before they elongated fully. Less than 24 hours were required for translocation of the virus throughout the plant. Based on results of this study the systemic translocation of barley yellow dwarf virus is probably not a useful measure of host plant resistance or tolerance.
